Most healthcare professionals agree that breastfeeding is preferable to bottle feeding because it has many benefits for both you and your baby.

If you are considering changing over from breastfeeding or combining breast and bottle feeding, you are advised to talk to your midwife or health visitor first. Once the decision to stop breastfeeding has been made, it may be difficult to go back.
Partial bottle feeding with an infant formula milk, especially in the first few weeks of life, may also reduce the supply of your breast milk.

If you choose to bottle feed, it is very important that you use an infant formula milk throughout the first year.
